  56 #       SEPARATE_GOTPLT - if set, .got.plt should be separate output section,
  57 #               so that .got can be in the RELRO area.  It should be set to
  58 #               the number of bytes in the beginning of .got.plt which can be
  59 #               in the RELRO area as well.

  63 #
  64 # When adding sections, do note that the names of some sections are used
  65 # when specifying the start address of the next.
  66 #
  67
  68 #  Many sections come in three flavours.  There is the 'real' section,
  69 #  like ".data".  Then there are the per-procedure or per-variable
  70 #  sections, generated by -ffunction-sections and -fdata-sections in GCC,
  71 #  and useful for --gc-sections, which for a variable "foo" might be
  72 #  ".data.foo".  Then there are the linkonce sections, for which the linker
  73 #  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
  74 #  The exact correspondences are:
  75 #
  76 #  Section      Linkonce section
  77 #  .text        .gnu.linkonce.t.foo
  78 #  .rodata      .gnu.linkonce.r.foo
  79 #  .data        .gnu.linkonce.d.foo
  80 #  .bss         .gnu.linkonce.b.foo
  81 #  .sdata       .gnu.linkonce.s.foo
  82 #  .sbss        .gnu.linkonce.sb.foo
  83 #  .sdata2      .gnu.linkonce.s2.foo
  84 #  .sbss2       .gnu.linkonce.sb2.foo
  85 #  .debug_info  .gnu.linkonce.wi.foo
  86 #  .tdata       .gnu.linkonce.td.foo
  87 #  .tbss        .gnu.linkonce.tb.foo
  88 #  .lrodata     .gnu.linkonce.lr.foo
  89 #  .ldata       .gnu.linkonce.l.foo
  90 #  .lbss        .gnu.linkonce.lb.foo
  91 #
  92 #  Each of these can also have corresponding .rel.* and .rela.* sections.
